" 'fii'fglai s. (01. 160-91) 1 storm sash.

Referring now to the drawings, it will be seen that the present combination storm and screen sash makes use of an outer rectangular frame, generally designated by the numeral llLandcomposed of a pair of spaced parallel side members H, an upper'end member 12, and alower'end member 13. The separate members comprising the router frameapossess identical transverse cross-sectional configurations, and. are Initered at their respective. ends andmigidly joinedwithone another, as by .means of metallic straps l4, orby other suitable .means, such as .Weldingor thermally-fusingthe members together.

Carried betweenthe side members i! of.,the outer frame, intermediate their; ends is a perpendicularly extending cross ,or mullion bar 15.

Referring particularly. to ,Figs. 2, and 4 of the drawing, ;each .of the; side. and BlHdJILQlI PE TS 19 the outer frame are formedalong their outer edges with l outwardly extending, relatively recluced coextensive flanges ltwhich are formed upon their inner side surfaceswith aplurality of serrations, and which. are adapted to engage the outer side surfacescof .a window casementor framefll. In addition to, the frictional engage- -ment obtainedthrough. the serrated edge ofthe flanges 5, it is comprehended that additional securing. means, such as: screws or;other suitable fastening devicespnot showmmay be employed in securely fasteningtheflanges, it along theupper and side portions of the Window frame ll. The

lower end member 1310f. the outer frame preferably has itsouter flange lfi secured to the sill portion l8.of the window-frame; bymeansmof-a the side and end members ofthe outer frame are formed with relatively reduced inwardly directed and coextensive flanges 20 which. definewith the body portions of therrnembers an abuttingshoulder. and-ledge opening toward the c entral -portion of.1 the;outer frame. Formed along the inner edges of eachof the members of the outerfrarne are I coextensive, substantially V shaped. grooves or--recesses ,2 I which: open toward, thededge provided; between the body of -.themembers and, the l ni-l'ip the V-shaped grooves 2| are additionally formed lip 3| toward the open portion thereof.

frame 38.

with a notched recess 22 in which is positioned an outwardly and laterally projecting shoulder 33 formed along the base portion of a plurality of how spring glazing splines 24. Each of the glazing splines 24 functions to engage the marginal edge portion of a transparent pane member 25 which is positioned in abutting engagement with the inwardly directed flanges of the upper end and side members of the outer frame.

Advantageously, the marginal edge portions of the pane may be cushioned within a body of suitable mastic 26 to prevent direct frictional engagement between the edges of the pane and the inwardly directed flanges 20 of the side and upper end members of the outer frame.

The cross bar I5 is formed along its upper edge portion identically to the inner edge portions of the side and end members of the outer frame, in that the same is provided with a relatively reduced and upwardly extending flange 21, a coextensive V-shaped recess 28 which is provided with a notched recess 23 for the reception of the outwardly projecting shoulder 23 of an associated glazing spline 2d. The upperend portion of the cross-bar l5 receives the lower marginal edge of the pane 25 in the same manner as do the inwardly directed edge portions of the side and upper end members of the outer frame.

Additionally, the side and end members or the outer frame, and the cross bar 15 are formed upon their outer side surfaces with recessed coextensive and communicating slots or cavities '30 which are undercut to provide an abutment The undercut slots 30 of the cross bar, side members and lower end member receive the marginal edge portions of a rectangular flexible .screen member 32 which is provided along its marginal edges with a continuous substantially rectangular stiffening frame 33 preferably formed from'metallic wire or other material capable of resiliently bending or stretchin when pressed within the slots 30. The abutment lip 3| provided by the undercut of the slots 30 functions to maintain .the stiffening frame 33 of the screen member 32 within the slots when the same is resiliently stretched and snapped therein to prevent the same from accidental withdrawal. However, it

will be understood that the screen member 32 may be detached from the lower section of the outer frame by means of hand pressure applied to lift the members of the stiffening frame 33 out of engagement with the abutment lip 31. Toward this end, a screw driver or other suitable tool may advantageously be inserted within the slots 30 for the purpose of withdrawing the stiffening frame therefrom.

The mullion or cross bar 15 is formed along its lower edge with a relatively reduced downwardly projecting and coextensive flange v34 which defines with the body portion of the lower edge of the cross bar a substantially perpendicularly walled recess 35, in which is formed a downwardly opening coextensive groove'36.

Carried between the lower edge of the cross 'bar 15, the side members and the lower end member of the outer frame is a removable transparent pane member 31 which is provided along its outer marginal edges with a rectangular outer The outer frame 38 of the lower pane is formed along its inner edges in the same manner as the inner edge portions of the side and end members of the outer frame It, in'that fthe'same is provided with pane-abutting flanges :39, and V-shaped notches 43 formed for the reception of glazing splines 24. By the same tcxen, the marginal edge portions of the lower pane 3'! are cushioned within its outer frame 38 by a body of mastic compound in the manner of the upper pane. The outer frame 38 of the lower pane is provided along its upper edge with a tapered upwardly projecting tongue H for insertion within the groove 36 provided in the lower edge of the cross bar l5. Advantageously, the taper of the tongue ll begins substantially at the outer end of the groove 36, whereby the lower pane member 31 may be removed from the lower section of the outer frame ill by pulling inwardly upon a pair of handle members 42 carried upon the lower end member of the frame 38.

As shown in Figs. 2, 4 and 5, the side and end members of the outer frame 38 of the lower pane are identical in cross-sectional configuration, and are carried in abutting and frictional engagement with the inwardly directed flanges 20 of the lower end and side members of the outer frame it and the downwardly projecting flange 34 0f the cross bar IS. The lower pane member and its outer frame are supported between the cross bar and the lower end member of the outer frame 13 upon the ledge portions of the edges of these members, and preferably in tight-fitting irlctional engagement therewith.

It will be here understood, that either the upper or lower sections of the outer frame may be provided with detachable pane members and screen members, but in a preferred assembly, the detachable screen and panes are provided to cover the lower section of the sash only, with the upper section being permanently covered by means or" the single upper pane 25.

In view of the foregoing, it will be seen that the present combination storm and screen sash lends itself to mass production facilities through the embodiment of identical cross-sectional outer frame members which may advantageously be, and readily lend themselves to, extrusion processes and may thus be formed in continuous lengths or strips to be subsequently cut in conformity with the dimensions of a given window frame or window opening. By the same token, the outer framemembers of the removable pane section possess identical cross-sectional configurations and may likewise be extruded into prefabricated strips to be readily assembled according to size.

A sash formed in accordance with the present invention utilizes as its various frame members only 3 extruded sections, namely the members forming the outer frame of the sash, the cross bar, and the individual frame members of the removal pane. The fact that such members may be'readily formed from extrusion processes greatly reduces the cost of the present combination storm and screen sash, and enables the same to 'be quickly and easily fabricated with consequent reduction in labor costs. Preferably, the various frame members utilized in the present sash construction are formed from lightweight metals or alloys, such as aluminum or magnesium, or various alloys thereof, which "are characterized by their non-oxidising and weatherresistant properties. Sashes formed in accordance with the present invention are further characterized by their attractive and neat appearance made "possible through the overlapping nature of the outer flanges of the side and end members of the outer frame 'and'the cross bar portion thereof.

One particularly important feature of the present invention resides in the provision of a storm sash which may simultaneously receive both a screen member and a removable pane section, whereby the user is not required periodically to exchange one section for the other, the screen member, if desired, being left in its operative position throughout the various seasons of the year.

While a single preferred embodiment of the invention has been disclosed in considerable detail, it will be manifest that modifications with regard to constructional details may be made without departing from the spirit of the invention or the scope of the following claims.
